SPECIFICATION forming part of Letters Patent No. 661,243, dated November 6, 1900. Application fuea february 19. 1900. serai No. 5,813. uw model.)

To all whom, it may concern.-

Beit known that I, EMIL GAHLAU, acitizen of the United States, residing at Detroit, in the county of Vayne and State of Michigan,

have invented certain new and useful Improvements in LampGuards, of which the following is a specification, reference being had therein to the accompanying drawings.

Hy invention relates to lamp-guards; and io the invention consists in the peculiar construction of the means for securing the guard to the lamp-socket and, further, in the construction of the body of the guard, as more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of my lamp-guard. Fig. 2 is a side elevation of the clamping means, showing the same in engagement with the lamp-socket. Fig. 3 is a section on line au, Fig. 2. Fig. et is a side elevation of the guard, showing it open to receive the lamp.

Ais the body ofthe guard, which surrounds the lamp-bulb. This is formed by a Wire ring B, arranged in a horizontal plane or one perpendicular to the longitudinal axis of the lamp and provided with a series of loops or eyes a. To these eyes are secured the ends of a series of loops C, said loops intermeshing` with each other and being adapted to be turned into the position shown in Fig. l, in which they form a spherical basket, or to be opened into the position shown in Fig. 4:, so as to permit ofsecuring the lamp in its socket. The ends of said loops C are provided with hooks or eyes b, engaging with the eyes a,

which latter prevent the loops from being displaced in relation to each other.

D represents upwardly-extending arms comprising wire loops, connected at their lower ends by eyes c with the ring B and at their upper ends having the segmental portion cl. At the ends of the segmental portion d are the substantially parallel longitudinal portions e, and beneath these vertical portions are the oppositely-inclined portions f, the arrangement being such that the eyes c are spaced substantially equal distances from each other around the ring B, while the segment d and longitudinal portion e form bearings upon the lamp-socket.

E represents segmental arms formed of wire loops having the eyes gat theirends connected to one of the longitudinal portions e of each arm D. The segmental portion of each arm E is of a length to extend half-way around the lamp-socket and is provided with a hook 7L, adapted to engage with the portion e of the opposite arm D between the eyes g of the opposite segmental arm E. Beyond the hooks h is a slightly outwardly bent portion z', form- 6o ing a catch for engaging or disengaging the hooks h from the arm D.

The guard being constructed as shown and described,to engage it with the lamp-'socket the 'arms D are spread apart a sufcient distance 65 to pass over said socket and are then pressed together, after which the arms E are swung in around the socket and the hooks h are engaged with the opposite longitudinal portions e, the intermediate portions d being clamped 7o between said arm and the lamp-socket. This will securely lock the guard to the socket. When it is desired to remove or replace the lamp-bulb, this may be done without disengaging the guard by simply spreading the loops of the body A into the position shown in Fig. 4. In this position, if desired, the guard may be used for holding a shade, or it may be turned into any position desired intermediate the positions shown in Figs. 4 and l. The 8o eyes u, serve to' hold the loops C in their proper relative positions and also form a better hinge connection between said loops and the ring B.

By forming the arms D of a simple loop of wire bent into the form described and the clamping-segments also of a loop the cost of manufacture is reduced to the minimum. At the same time as both the segmental portions d and longitudinal portions e of the arms D bear against the lamp-socket and as the arms 9o E clamp all of said bearing portions against said socket the guard is securely held in position.

What I claim as my invention is- 1. A lamp-guardcomprising a body, arms hinged thereto adapted to extend upon opposite sides of the lam p-socket, each'ot' said arms consisting of a wire loop having longitudinal bearing portions and a connecting segmental portion; and semicircular locking-segments 10o hinged to the longitudinal portions at one side of each arm having hooks at their free ends 2 eeL43 r ing eyes at its endsengaging with one of said longitudinal portions, and a hook at its free end for engaging With the corresponding bearing of the opposite arm between the eyes of i5 the opposite hinged segment.

In testimony whereof I affix my signature in presence of two Witnesses.
